MINING UNITS

MINE - I INCLUDING EXPANSION:

The lignite seam was first exposed in August 1961 and regular mining of lignite commenced in May 1962 with a capacity of 6.5 MTPA. German excavation technology in open cast mining, using Bucket Wheel Excavators, Conveyors and Spreaders were used for the first time in the country in Neyveli Mine-I. The capacity was increased to 10.5MT of lignite per annum from March 2003 under Mine-I expansion scheme and at present meets the fuel requirement for generating power from TPS-I and TPS-I Expansion.

MINE - II INCLUDING EXPANSION:

In February, 1978 Government of India sanctioned the Second Lignite Mine of capacity 4.7 MT of lignite per annum and in February `83, Government of India sanctioned the expansion of Second Mine capacity from 4.7 Million Tonnes to 10.5 Million Tonnes. GOI sanctioned the expansion of Mine-II from 10.5 MTPA to 15.0 MTPA of lignite in October 2004 with a cost of Rs. 2295.93 crore. Mine-II Expansion project was completed on 12th March 2010. The lignite excavated from Mine-II meets the fuel requirements of Thermal Power Station-II and Thermal Power Station–II Ist Expansion.

MINE IA AND EXPANSION :

Mine IA with a capacity of 3.0 MTPA was commenced on 30th july 2001 & lignite production commenced on 30th March 2003.Mine IA meets the fuel requirement of 250 MW Independent Power project at Neyveli and also for commercial advantage. Further in the year 2015 expansion was approved to increase the capacity from 3.0 to 7.0 MTPA to cater the NNTPS(Neyveli New Thermal Power Station) fuel requirement.

TALABIRA II & III OCP:

GOT, MOC, allotted Talabira –II & III coal block in favour of NLCIndia Limited on 02/05/2016.The block is having 553.98 MT of Coal reserves. Capacity of Mine :20 MTPA (Normative),Peak 23 MTPA .The block is operated by MDO.MDO has been engaged for Talabira – II & III.The coal from the block caters the needs of coal based pithead TPS( 5 * 800MW) in 2 Phases and NTPL (2 * 500 MW ),Tuticorin.

BARSINGSAR MINE:

GOI sanctioned implementation of Barsingsar mine with a capacity of 2.1 MTPA of lignite per annum at an estimated cost of Rs. 254.60 crore in December 2004. Both overburden and lignite production has been outsourced. Lignite excavation commenced on 23rd November 2009 and production attained the rated capacity on 31st January 2010.

THERMAL POWER STATIONS

THERMAL POWER STATION-I:

The 600MW Neyveli Thermal Power Station-I in which the first unit was synchronized in May'62 and the last unit in September'70 consists of six units of 50 MW each and three units of 100 MW each. The Power generated from Thermal Power Station-I after meeting NLC's requirements is fed into Tamil Nadu Electricity Board which is the sole beneficiary. In view of the high grid demand in this region, this power station is being operated after conducting Residual Life Assessment (RLA) study. GOI has sanctioned a 2x500 MW Power Project (Neyveli New Thermal Power Plant – NNTPS) in June 2011 as replacement for existing TPS-I. In view of certain technocal issuses and ageing, 100 MW was stopped and plant was derated to 500 MW. The Plant is proposed to be stopped after the Commissioning of NNTPS.

THERMAL POWER STATION-II:

The 1470MW Second Thermal Power Station consists of 7 units of 210 MW each. The first 210 MW unit was synchronised in March 1986 and the last unit (Unit-VII) was synchronized in June'93. The power generated from Second Thermal Power Station after meeting the needs of Second Mine is shared by the Southern States viz., Tamil Nadu, Kerala, Karnataka, Andhra Pradesh and Union Territory of Pondicherry.

THERMAL POWER STATION-I EXPANSION:

Thermal Power Station-I has been expanded using the lignite available from Mine-I Expansion. The scheme was sanctioned by Government of India in February 1996. The Unit-I was synchronised in October 2002 and Unit-II in July 2003. The power generated from this Thermal Power Station after meeting the internal requirements is shared by the Southern States viz., Tamil Nadu, Kerala, Karnataka, and Union Territory of Pondicherry.

BARSINGSAR THERMAL POWER STATION:

Government of India sanctioned the Barsingsar Thermal Power Station 250 MW (2 X 125 MW) in October 2004. The steam generators of this project are ECO friendly “Circulating Fluidised Bed Combustion (CFBC) technology. The power generated from this thermal power station after meeting internal requirements is shared by the DISCOMS of the state of Rajasthan.

TPS-II EXPANSION

This Project is consisting of two units of 250 MW capacity each. The lignite requirement is met by Mine-II expansion. The steam generators of this project are ECO friendly “Circulating Fluidised Bed Combustion (CFBC) technology. This technology is being adopted for 250 MW Capacity units for the first time in India.

NLC TAMIL NADU POWER LIMITED(NTPL),TUTICORIN

NLC TAMILNADU POWER LIMITED (NTPL) coal based 2x500 MW thermal power plant at Tuticorin in Tamil Nadu is a joint venture company with TANGEDCO. NLC holds 89% of equity and TANGEDCO 11%. NTPL has signed a fuel supply agreement with Mahanadhi Coal fields Limited and Eastern Coalfield Limited for supply of coal. In case of any shortfall in supply, Imported coal is being blended.

PROJECTS

NEYVELI NEW THERMAL POWER PROJECT(NNTPP)

The Neyveli New Thermal Power Project (2x500 MW) is being implemented at a capital cost of Rs.5907.11 Cr as replacement for more than five decades old 600 MW Thermal Power Station I and adopts pulverized fuel firing technology. Contracts for Steam Generator package (NTA 1), Turbo-Generator package (NTA 2) and Balance of Plant Package were entered. The Project is in the final stage of commissioning, tentatively by March 2019 / May 2019.
